throughout :5 indicates l' usually pi ter, upon any preferre casir or noi fo ming substai n' for devices niennted i Li a cylinder for l`he' cylil .r 2 formed by the tions of the cas ne or housing is flat or cfreduced thickness ror the greater portion of its Drea, the outer portionthereof being inci; .sed7 as @vsn at 3 and designed s betantiallyrectangular in cross section. This outer portion of the cylinderindicated as 3, continues completely around the housing forming anannular enlarged space in which the gaseato be hereinafter referred. to,are received.

Mounted in the cylinder or housing 2., is a dislelike :intein-' whichlits snugly between the walls of. the flat reduced portion of saidcylinder and has formed on the outer pe ripheral edge thereof atpredetermined points thereon one or more head members or the like whichlit within the annular space of the latter. As many of these headmembers may be provided as are found desi rahle and thus the power ofthe device may be in creased accordingly and each of said head membersis provided with a plurality of extension members 5', as clearlydisclosed in Fig. l of the drawings. These. head members or project-ions5 on the rotor Il afford a against saidk head members and said head`nien/rivers are beveled at their ends, as shown The outer faces of saidhead members contact snugly with the outer peripheral. wall of theenlarged portion 3 of said cylinder and carried on the central portionof the dislnlilre rotor a to project through openings in the sides orsections of the cylinder, is a shaft 7. .Il dziustahly mounted on thebase orQ foundation l., on opposite sides of the cylinder, are thebearings 8 which ro. tataoly receive therein the projecting p0rtions ofthe shaft 7. As undue wear occurs between the sl ft, foundation andcylinder, the same may ne teiten up readily hy the adjustment of saidhearings 8, as is obvious, and pulley is carried on one end of saidshaft 7, whereby the power derived in the operation of the engine maybey transmitted to any desired device (not shown).

I have provided for the inlet of the eX- plosi-ve mixture or fluidpressure at the top of the cylinder or housing 2, at which point a pairof openings 9, arranged in spaced relation to one another, are provided.These form the actual inlet openings for the cylinder and a pair of thesame are provided in order to provide for the reversing of the rotor,which will be hereinafter and more particularly set forth. Mounted onthe housing or cylinder 2, over the openings 9, are the cylinders 10which form feed cylinders, the same being independent of one another andhai'ing connection at points below the centers thereof, with acarbureter 11 of any preferred design. As shown in Fig. 8 of thedrawings, the connections, between the carburetor and cylinders 10 maybe provided with suitable valves whereby the supply of the gaseousmixture to the cylinders may be regulated as desired. Arranged in eachof the cylinders lO in planes slightly below the centers thereof, arethe dividing walls 12 which provide a pair of compartments in eachcylinder and each division wall 12 is provided with a check valve 13,the purpose of which will be hereinafter and more particularly setforth. Hingedly mounted at the lower ends of said cylinders and openingdownwardly through Y the openings 9 in the cylinder or housing 2,

are the plate-like Valve members 14. These plate-like valve membersoperate oppositely in order to permit one of the same to be in itsinoperative position while the other is operating, and the side edges ofsaid plate-like valves are provided with side flanges 15 projecting onboth sides of the plate valve proper. These plate-like valve members .14are designed to complete the formation of the annular space inclosed bythe enlarged portion 3 of the cylinder 2 when said valve members aredisposed to their closed positions and the outer side edges of thesevalve members 14 project slightly beyond the side walls of theenlargements 3 of the cylinders and lit in offsets 15 formed in thelatter. This construction admits of the rotor being operated withoutinterference with said valve members-and in view of the constructionshown and described,y no appreciable amount of compression will vbelost.

Loosely extending through the top wall 12 of each of the cylinders 10 isa rod 16, the lower end of which is pivotally connected to a link 1,7,the latter in turn being pivotally connected to the upper face of avalve'membcr 14. The upper ends of said rods 16 are removably secured tothe hollow iston or plunger heads 18 which fit snugly mths cylinders 10and coil springs 19 are cylinders.

tact at their lower ends with the lower walls of the hollow piston heads18 and rigidly Secured at their upper ends to transverse pieces 20secured to the upper ends of said The normal tendency of these springsis to force downwardly upon the piston heads, which operation willobviously cause the valve members 14 to be opened and an adjusting means21 is provided in connection with the pieces 20 and the upper ends ofsaid springs, whereby the tension of the latter may be adjusted.Inasmuch as but one of the valve members 14 may be operated at a time, ameans is provided for retaining one valve member in .its closed positionat all times. This is accomplished by means of a rocking arm 19 which ismounted at the upper ends of said cylinders, the ends of which areindicated as 19a, project over the respective cylinders. Hook members19b are carried on the pistons 18 which are adapted to be engaged withthe ends 19, one at a time and as shown in Fig. 6 of the drawings, onepiston head 18 is 4hooked in its inoperative position, while the otheris operated.

It will be understood that as the rotor is revolved in the housing orcasing2, the head pieces or projections 5 thereon are adapted forcontact with the depending or open plate-like valve.14, to force thesame upwardly to its closed position. As the same is forced to itsclosed position, the rod 16 will be forced upwardly and the springs 19compressed. As the rod 16 is forced upwardly, the plunger or piston headlo thereon will also be raised and in so doing, a charge of gas will bereceived in the cylinder 1() from the carbureter 11.

As soon as the projection Ior head piece 5 passes the opening covered bythe valve member 14, said valve is forced by the pressure of the gaswithin the cylinder 10 and the action of the spring 19 to its openposition. As the valve is opened, the piston or plunger head 18 willalso be forced dmvnwardly to compress the gases against the divisionwall 12 and such compression will also open the check valve 13 andpermit said gases to be released to the lower compartment of thecylinder 10. In this lower compartment of the cylinder 10, at the lowerportion thereof, is mounted a spark plug 22 which is connected to asparking apparatus (not shown) in the usual or any preferred manner. Thedevice is so timed that the compressed gases which are forced into thelower compartment at this particular time will be fired and the force ofthe explosion directed against the adjacent face of the head orprojection 5 on the rotor 4 which, at this time, is at a pointimmediately adjacent the valve member 14. The space inclosed between theone face of theprojection or head member-5 on the ro tor and the valvemember-14, when the latter is in its lowered position may, forconvenience, at the time of the explosion, be termed a firing chamberand is indicated as 23. It might here be stated that this sparkingdevice is timed according to the osition of theV piston or plunger head18.

n order to carry out this purpose, a projection 23 is provided on thetransverse piece '2O of each` feed cylinderwhich has fulcruined thereon,a rocking arm 23. One end of the rocking arm is connected by means of alinlr 23" to the piston head in the adjacent cylinder and the other endof the rocking arm is connected by means of linking arm 23e to anydesired operating means (not shown) for cooperation with the sparkingdevice.

The force of the explosion will, of course, be directed against thebeveled face of the head member or projection 5 on the rotor to causethe latter to be revolved. The gases and other products of combustionwill be carried through lthe space inclosed by the` enlarged portion 3to a point on the device immediately opposite that in' which theopenings 9 are provided. An exhaust 2% is provided in the base l whichcommunicates with the annular space at such point and aords an outletfor the products of combustion and burnt gases. This operation may becontinued and when it is desired to reverse the operation of the rotor,the rocking arm 19 is disengaged from the one iston head 18 to which itwas engaged previously and rocked to the opposite position, and

linked or hooked into engagement with the piston head 10 which waspreviously in operation. The explosionswhich'will now take place in thedevice will be directed against the opposite 4faces of therotorprojections or heads 5 to cause the rotor to be rotated in the oppositedirection. The device will be actuated in identically the same manner asbefore but the direction thereof will be reversed.

The usual oiling devices and a Water jacket may be provided for thisengine, if desired. sary, a governor may also be used in connection withthe device.

While I have shown and'described my de vice particularly adapted Aforuse in connection with a carbureter, wherein explosive gases aresupplied to the feed cylinders of the device, it will be understood thatthe same may be operated through the medium of various other forms offuel. Fluid pressure is equally well adapted for use in connection withthis device and, of course, under these conditions, certain features ofthe device may be omitted. The device as shown, however, particularlyWell adapted' for use with a powder mixture andit- 'will be If it isfound desirable and necesunderstood that any form of explosive may beused in connection therewith.

From the foregoing it will be seen that I have provided a device whichis simple and durable in construction, inexpensive to manufacture andone which will be very eHicient and useful in operation. Vhile I haveparticularly described the elements best adapted to perform thefunctions set forth, it is obvious that various changes inform,proportion and in the minor details of construction may be resorted towithout departing from the spirit or sacrificing any of the principlesof the invention.
